I made this as my 3D printer attachment but I think it also looks cool on its own.
So i made a publish version for you guys.

It has some vents on the top and side. But don't worry i made it very easy to print without supports.
The cap is snap-on design and you can easily remove it without damaging it while you want to use the GPIO.
